“…Diversity statistics for nDNA loci ( RAG1 and β‐fibint7 ) indicated higher values of nucleotide and haplotype diversities in LCR compared to LHSF and HLCD clusters, whereas for mtDNA ( ND2 ), the nucleotide diversity was higher in LHCD and the haplotype diversity in LHSF. Our mtDNA haplotype scores for all region sampled were similar to frogs populations indices for northeastern Atlantic Forest ( Rhinella crucifer group: Thomé et al., 2010; Dendropsophus elegans : Tonini, Costa, & Carnaval, 2013: Scinax eurydice , Menezes et al., 2016: Atlantic Forest genus Pristimantis , Trevisan et al., 2020); however, our nucleotide diversity recovered was higher. The migration between LHCD and LCR clusters matches forest expansion and contraction events and agrees with the hypothesis of connection between Chapada Diamantina enclaves and Atlantic Forest in adjacent lowlands during the Pleistocene (Silveira et al., 2019).…”

Cyclical climatic changes during the Pleistocene produced glacial and interglacial periods that shaped spatial distribution and genetic composition of populations at high latitudes across the world (Alexandrino, Arntzen, & Ferrand, 2002; Milot, Gibbs, & Hobson, 2000). The importance of climatic fluctuations is easily acknowledged for temperate regions, where huge glaciers have contracted and expanded, repeatedly obliterating many species from most of their ranges. The role played by glaciations in tropical regions, such as those in South

“…In the case of new species in cryptic complexes, the multilocus approach has been favoured to provide more information and stability in the species descriptions (Neusser et al, 2011; Jörger et al, 2012; Borges & Merckelbach, 2018; Trevisan et al, 2020). The multilocus approach will also address the well‐known fact that gene trees are not necessarily identical to species trees, for instance because of incomplete lineage sorting or horizontal gene transfer (Jörger & Schrödl, 2013).…”

“…Moreover, Trevisan et al. (2020) found a remarkable hidden diversity in the genus Pristimantis from the northern Brazilian Atlantic Forest. Their analyses show that the populations of Pristimantis assigned to three nominal species represent nine highly structured lineages that may correspond to undescribed species.…”

"Eleutherodactylus" bilineatus has long been an enigma. Recent phylogenetic analyses have recovered this species as part of a clade including Barycholos and Noblella, but the relationship among these groups still remains contentious. In this study, we test the phylogenetic position and reassess the taxonomic status of this long-term incertae sedis species. We use phylogenetic analyses of nuclear and mitochondrial gene sequences and data for external morphology and osteology of "E." bilineatus and its related genera. We recover the species as an independent lineage forming a fully supported clade with Barycholos and Noblella. The combination of inferred relationships and morphological traits supports the erection of a new genus that we name and diagnose. Our analyses also recover a non-monophyletic Noblella and the species of the genus, although morphologically similar, are part of different clades: one including species from central Andes and the other one including species from northern Andes. Moreover, distribution patterns point out connections among distant biogeographical areas of South America and a widespread distribution of an ancestor for the clade including Barycholos, "E." bilineatus, and Noblella. We also compare the relationships among clades of Brachycephaloidea and, hence, the family and subfamily classifications in different studies. We show that the family classification is probably far from becoming stable, mostly due to arbitrary selections of hierarchy of the clades. However, we show that by assigning a family to each of the highly supported and frequently recovered clades would render a more stable taxonomy of Brachycephaloidea.
